Definitions

  • the present invention relates to a ball valve configured for shearing a body upon closure.
  • the present invention in particular, but not exclusively, relates to a ball valve for use in a landing string arrangement, for example for use within a subsea test tree.
  • Landing strings are used in the oil and gas industry for through-riser deployment of equipment, such as completion architecture, well testing equipment, intervention tooling and the like into a subsea well from a surface vessel.
  • equipment such as completion architecture, well testing equipment, intervention tooling and the like into a subsea well from a surface vessel.
  • the landing string When in a deployed configuration the landing string extends between the surface vessel and the wellhead, for example a wellhead Blow Out Preventor (BOP).
  • BOP Blow Out Preventor
  • While deployed the landing string provides many functions, including permitting the safe deployment of wireline or coiled tubing equipment through the landing string and into the well, providing the necessary primary well control barriers and permitting emergency disconnect while isolating both the well and landing string.
  • Wireline or coiled tubing deployment may be facilitated via a lubricator valve which is located proximate the surface vessel, for example below a rig floor.
  • valves typically ball valves
  • the valve suite includes a lower valve assembly called the subsea test tree (SSTT) which provides a safety barrier to contain well pressure, and an upper valve assembly called the retainer valve which isolates the landing string contents and can be used to vent trapped pressure from between the retainer valve and SSTT.
  • SSTT subsea test tree
  • a shear sub component extends between the retainer valve and SSTT which is capable of being sheared by the BOP if required.
  • the landing string may accommodate wireline and/or coiled tubing deployed tools.
  • the various valve assemblies such as in the SSTT, must define sufficiently large internal diameters to permit unrestricted passage therethrough.
  • the valve assemblies also have outer diameter limitations, for example as they must be locatable within the wellhead BOP. Such conflicting design requirements may create difficulty in, for example, achieving appropriate valve sealing, as increasing the internal diameter within a restricted outer diameter may only permit minimal a sealing area to be provided.
  • a ball is provided with a throughbore, wherein an edge of the throughbore functions to cut through wireline or coiled tubing upon rotation of the ball towards a closed configuration.
  • Known ball valve designs are such that the throughbore is circular providing a correspondingly shaped throughbore edge.
  • the present inventors have discovered that, particularly with coiled tubing, the cutting forces are applied initially centrally of the tubing, causing the tubing to collapse, making subsequent shearing of the collapsed tube difficult and energy/force intensive.
  • the landing string must also be designed to accommodate the significant in- service loadings, such as the global tension from a supported lower string (e.g., a test string, completion or the like), bending loads, valve actuation loading, internal and external pressures and the like.
  • a supported lower string e.g., a test string, completion or the like
  • bending loads e.g., a test string, completion or the like
  • valve actuation loading e.g., internal and external pressures and the like.
  • internal and external pressures e.g., internal and external pressures and the like.
  • landing string global tension requirements far in excess of 4.5MN (1 ,000,000 Ibf) and wellbore pressures which can exceed 690 bar (10,000 psi) are typical.
  • Such loadings must be accommodated across regions including the various valve assemblies, such as the SSTT.
  • valve housings and appropriate end connections it is therefore necessary to design the valve housings and appropriate end connections to be capable of accommodating the global applied tension, bending loads, valve actuation loading and pressures. This results in the use of thick walled valve housings, which can compromise the achievable valve internal diameters and sealing integrity.
  • connections through such landing string valve assemblies may include bolted connections of the valve housings into the landing string. This typically requires significant upsizing of the connections and establishes further difficulties in achieving sufficiently large internal diameters within the outer diameter constraints, such as dictated by the BOP.
  • a ball valve comprising:
  • a ball member mounted within the housing and being rotatable relative to the ball seat between open and closed positions;
  • the ball seat and ball member define respective through bores each having a bore edge, and wherein the bore edge of at least one of the valve seat and ball member defines a recessed cutting region for cutting a body extending at least partially through the valve upon closure of the ball member.
  • the respective through bores of the ball seat and ball member may define a flow path through the valve.
  • the ball member may be rotated relative to the ball seat to misalign the respective through bores to prevent or restrict flow through the valve, and may be rotated relative to the ball seat to align, for example coaxially align, the respective through bores to permit or increase flow through the valve.
  • closure of the ball member to prevent or restrict flow through the valve may also result in any body which at least partially extends through the valve being cut, for example partially or fully cut. This arrangement may permit full closure of the valve member to be achieved without impedance from the body.
  • the ball valve may have numerous applications as might readily be understood by those of skill in the art.
  • the ball valve may be configured for use within a landing string assembly.
  • the ball valve may define or form part of a Subsea Test Tree (SSTT), a retainer valve, a lubricator valve or the like.

  • a recessed cutting region may be configured to cut, for example effectively cut, a generally circular body.
  • the body may extend at least partially through the respective through bores of the ball seat and ball member.
  • the body may extend entirely through the respective through bores of the ball seat and ball member.
  • the through bores of the ball seat and ball member may be configured to accommodate a body to extend at least partially therethrough.
  • Both the ball seat and ball member may define a recessed cutting region. In such an arrangement the respective recessed cutting regions may be configured similarly, or differently.
  • Respective recessed cutting regions of the ball seat and ball member may be generally aligned with each other. Such alignment may be considered to exist in a plane which is perpendicular to a rotational axis of the ball member. In other embodiments the respective recessed cutting regions of the ball seat and ball member may be misaligned.
  • Only one of the ball seat and ball member may define a recessed cutting region. This arrangement may be advantageous in that the component which does not comprise a cutting recess may hold the body being cut in a more central position relative to the ball seat and ball member, presenting the body in a better position to be cut. In one embodiment only the ball member may define a recessed cutting region.
  • a recessed cutting region may be recessed relative to an associated through bore. That is, the recessed cutting region may be outwardly recessed relative to an associate throughbore.
  • a recessed cutting region may be configured to at least partially receive a body to be cut.
  • the recessed cutting region may be configured to entirely receive a body to be cut.
  • large bodies for example large diameter bodies may only partially be received within the recessed cutting region.
  • the ball valve may comprise one or more inserts located within a recessed cutting region.
  • the insert may define a cutting edge. Such an insert may facilitate easier maintenance and the like. For example, to re-establish a sufficient cutting edge only the insert need be replaced, rather than the entire ball.
  • the ball member may define a sealing area which cooperates with an appropriate sealing area of the ball seat, at least when the valve is in a closed configuration.
  • the ball seal area is rotationally offset from the ball through bore.
  • the recessed cutting region may be defined within the ball member, wherein said cutting region is recessed towards the sealing area.
  • the housing may be configured to be secured in-line with a fluid conduit system, wherein the ball seat and ball member may cooperate to control flow along the fluid conduit system.
  • the fluid conduit system may be defined by one or more tubing components, flow equipment such as other valves, flow meters, shear-sub components or the like.
  • the housing may be configured to be secured in-line with a landing string.
  • the housing may comprise first and second connectors for securing in-line with a fluid conduit system, such as a landing string. At least one of the first and second connectors may comprise a flange connector, such as a bolted flange connector.
  • the first and second connectors may be configured to be secured to a similar component, such as tubing, for example.
  • the first and second connectors may be configured to be secured to different components. For example, one connector may be configured to be secured to tubing, and one connector may be configured to be secured to flow equipment such as another valve or the like.
  • the housing may comprise a unitary component.
  • the housing may comprise multiple components.
  • the housing may comprise an outer housing configured to be mechanically secured in-line with a fluid conduit system and an inner housing located within the outer housing and configured to contain pressure.
  • the outer housing may be defined as a structural housing. That is, the outer housing may be provided primarily to accommodate mechanical forces, such as axial and bending forces, associated with the fluid conduit system while providing minimal or no pressure containment, for example of internal and/or external pressures.
  • the inner housing may be defined as a pressure housing. That is, the inner housing may be provided primarily for pressure containment, for example of internal and/or external pressures, while providing minimal or no contribution to accommodating mechanical loading associated with the fluid conduit system This arrangement may permit each individual housing to be designed and/or selected to meet more focussed or specific operational requirements. These divided roles of the first and second housings may provide a number of advantages, such as reduction in wall thickness, weight, costs and the like.
  • an outer structural housing and a separate pressure containing inner housing may permit a reduction in the global housing wall thickness to be achieved. That is, as the outer housing is not intended to be pressure containing, the wall thickness of this can be significantly reduced. Furthermore, as the inner housing is intended for pressure containment, and not, for example, to accommodate significant tensile and bending loads, this too can have a minimal wall thickness for its limited function. As such, the combined wall thickness can be reduced relative to a single structure which is designed to be exposed to both mechanical and pressure loading.
  • Reducing the overall wall thickness of the housing may permit a larger housing inner diameter to be available allowing one or both of the ball seat and ball member to be increased in size. This may be particularly advantageous in permitting a sufficient valve sealing area to be achieved even with the presence of a recessed cutting region. That is, the recessed cutting region may encroach into a sealing area of the ball seat and/or ball member, wherein an increased ball seat and/or ball member, and associated sealing area may permit such encroachment to be accommodated without compromising sealing integrity.
  • mechanical forces such as tensile forces and bending forces, may be transmitted across the outer housing.
  • Such mechanical forces may originate from the fluid conduit system, such as from the weight of the fluid conduit system or the like.
  • the outer housing may comprise a connection arrangement for permitting mechanical connection with a fluid conduit system.
  • the connection arrangement may comprise first and second connectors for securing in-line with a fluid conduit system. At least one of the first and second connectors may comprise a flange connector. At least one of the first and second connectors may define a preloaded connector. Such preloading may be achieved by use of one or more preloaded bolt connections. Such preloading may permit the point of connection from separating during use, for example due to axial and bending forces.
  • any requirement to provide such a preloaded connector with the inner housing is eliminated. That is, only the connection between the outer housing and the fluid conduit system may require preloading, for example to meet required or preferred industry standards.
  • the inner housing may be axially contained within the outer housing. In such an arrangement any axial loading experienced by the inner housing, for example due to internal pressures, valve actuation forces and the like may be transferred to the outer housing.
  • the inner housing may be axially contained between first and second connectors of the outer housing.
  • the outer housing may comprise an axially extending wall section configured to encapsulate the inner housing. As pressure forces are contained primarily by the inner housing, the wall thickness of the axially extending wall section of the outer housing may be minimised.
  • the outer housing may define a barrel-type housing.
  • the housing segments may be secured together by a bolting arrangement.
  • the bolting arrangement may be provided along one or more sides or regions of separation between different segments.
  • the housing segments may be secured together via one or more tangential bolts.
